READING-LIGHT.

Specification of Letters Patent.

Patented Nov. 12, rate.

Application filed August 2, 1918. Serial No. 248,023.

To all whom it may concern:

Be it known that 1, JOHN P. SUTTER, a citizen of the United States, and resident of Bufialo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Reading-Lights, of which the following is a specification.

' This invention relates to the class of lighting fixtures, and more particularly to an improved portable reading light or lamp, adapted to be applied to a hook, drawing board or the like, for rendering clearly visible the matter thereon, so that one can read comfortably and without eye strain.

A further object of the invention is to provide an improved reading light of the class described including a shade or reflector of novel construction and shape, having 1mproved means for detachably engaging the object to which the device is to be applied for reading purposes, the source of illumination being preferably electrical.

lVith the above and other objects in view, as will appear as, the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described herein and set forth with particularity in the claim appended hereto.

Reference is had to the accompanying drawings forming a part of this application, in which like reference characters indicate the corresponding parts throughout the several views, in which- Figure 1 is a rear elevation of my improved reading light,

Fig. 2 is a plan view thereof, and

on the line 33 of Fig. 1.

Referring to the drawings in detail, my improved reading light is shown as comprising a reflector preferably substantially of triangular cross section having a top wall 11 and a rear wall 12, slightly providing concaved or rounded curved and corn portions 13 and M designed to facilireiiection of the iight towa the portion 15, which is incl do nwardiy to he 1 3 is a vertical sectional view takenoutwardly and forwardly, and inasmuch as the reflector is made of light sheet metal or other suitable material provided with an interior reflecting surface, the light will be thrown outwardly and downwardly upon the object to be supplied with illumination, for reading or other purposes.

The source of illumination may consist of an electric light bulb 18 mounted within the rounded corner portion 13, centrally between the top portion 11 and the back portion 12, the same having connection with a suitable source of electrical energy, consisting of a primary battery, a secondary battery, or the ordinary commercial lighting circuit, in which latterinstance a resistance element or rheostat may be interposed in the circuit, owing to the ininuteness of the lamp required to provide the proper degree of illumination. 7 I In order to detachably secure the device to a book, drawing board, or the like, a clamp is provided consisting of a plate 19 riveted to the bottom portion 16, as shown at 20, and having a plate 21 hinged thereto, preferably by providing oppositely extending apertured lugs or ears 22 upon the respective plates connected by a pivot pin 23 with an interposed spring 24 designed to normally dispose the clamping jaws 25 of the plates 19 and 21 in clamping relation. The plates are also provided with reduced handle portions 26, so as to permit the clamp to be readily manipulated.

Also, in view of the shape of the reflector, a maximum quantity of light uniformly distributed over the surface to be observed or read can be given, and the device can be easily applied and removed. Also, by reason of the portability of the device, it can be connected with a battery and thereby serve to permit reading outdoors, especially in hot summer evenings, instead of necessitating that one remain indoors. The weight of the device is also negligible, even including dry cell which in y be used for supp ing the proper anion, t of cnrrent to the in, througi the of ordinary neai electrical con ection. The device can be used in d ia-etc-ries or offices whe poor, for ream operation, and advantages of my invention may be had, and While I have shown and described the device asembodying a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope.

of the invention as claimed.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is:

A reading lamp, comprising a reflector of substantially triangular cross section having a top Wall and a rear wall sloping slightly forwardly and provided with rounded'upper and lower corners and a bottom portion, said reflector having end walls diverging forwardly and inclined toward said bottom Wall at their side edges, and a clamp including spaced plates pivotally connected and spring means between said plates to normally dispose the same in clamping relation, said clamp being riveted to the bottom portion cat the reflector and extending forwardly and rearwardly of the said bottom portion, as and for the purposes specified.

In testimony whereof I aflix my signature hereto.

JOHN P. SUTTER.
